Definitions

  • Multi-layers of ⁇ -Al 2 O 3 and Ti(C,O) or ⁇ -Al 2 O 3 and TiN have proved to exhibit better wear properties than single oxide layers, see U.S. Pat. No. 5,700,569 and U.S. Ser. No. 09/717,006.
  • Ti(C,N) exhibits better wear resistance against crater wear and flank wear in hypoeutectoid steels than TiN (U.S. Ser. No. 09/207,687).
  • Ti(C,N) is better that TiN, especially with respect to flank wear.
  • Al 2 O 3 is a superior coating material against crater wear.
  • adhesion of both ⁇ and ⁇ phases to the MTCVD Ti(C,N) deposited at 800° C. is surprisingly good.
  • a coated body wherein the coating comprises a multi-layer of ⁇ -Al 2 O 3 .
  • a coated body wherein the coating comprises a multi-layer of ⁇ -Al 2 O 3 and/or ⁇ -Al 2 O 3 layers interspersed with layers of Ti(C,N) on a layer of Ti(C,N).
  • a coated body wherein the coating comprises a multi-layer of ⁇ -Al 2 O 3 and ⁇ -Al 2 O 3 , each applied by a chemical vapor deposition at a temperature of from 700 to 900° C.
  • a coated body wherein the coating comprises a multi-layer of ⁇ -Al 2 O 3 and/or ⁇ -Al 2 O 3 layers interspersed with layers of Ti(C,N) on a layer of Ti(C,N).
  • a coated body wherein the coated comprises a multi-layer of ⁇ -Al 2 O 3 and/or ⁇ -Al 2 O 3 layers interspersed with layers of Ti(C,N) on a layer of Ti(C,N) and with a layer of Ti(C,N) atop of the said multi-layer.
  • FIG. 1 is a representation of a coated body of the present invention including ⁇ -Al 2 O 3 multi-layers (FIG. 1 a ), ⁇ -Al 2 O 3 with multi-layers (FIG. 1 b ) and a mixed ⁇ - and ⁇ -Al 2 O 3 multi-layer (FIG. 1 c ).
  • FIG. 2 is a representation of a coated body of the present invention useful in cutting of SS1672 (FIG. 2 a ) and SS2258 (FIG. 2 b ).
  • FIG. 3 shows Scanning Electron Microscope (SEM) images of the cutting edges of single and multi-layer ⁇ -Al 2 O 3 coated inserts after turning of 2, 5 and 8 minutes (9 minutes for the multi-layer ⁇ -Al 2 O 3 coated insert) of SS2258.
  • SEM Scanning Electron Microscope
  • FIG. 4 shows Scanning Electron Microscope (SEM) images of the cutting edges of single and multi-layer ⁇ -Al 2 O 3 coated inserts after turning of 2, 9 and 15 minutes of SS1678.
  • FIG. 1 shows a schematic of the coating layer according to this invention.
  • the coating is composed of the following layers:
  • Multi-layer structure consisting of ⁇ -Al 2 O 3 (FIG. 1 a ), ⁇ -Al 2 O 3 (FIG. 1 b ) or both (FIG. 1 c ), together with MTCVD Ti(C,N) interlayers, all deposited at a temperature of 800-900° C.
  • the wear properties of ⁇ are not yet fully elucidated. However, ⁇ is a less stable phase than ⁇ and can be used only in the uppermost layers of the multi-coating structure which will be subjected to the shortest annealing during deposition.
  • the Al 2 O 3 layers in the multi-layer (whether ⁇ or ⁇ ) have an individual thickness of from about 0.1 to 3.2 microns, preferably about 0.3 to 1.2 microns.
  • the Ti(C,N) layers in the multi-layer have an individual thickness of from about 0.1 to about 3.2 microns, preferably from about 0.3 to about 1.2 microns.
  • the total thickness of the multi-layer is from about 3 to about 30 microns, preferably from about 5 to 15 microns.
  • the multi-layer may also be deposited onto a Ti(C,N) layer of from about 2 to about 15 microns, preferably from about 3 to 10 microns, which in this instance is the first layer applied onto the body.
  • a Ti(C,N) layer of the same thickness can be deposited atop the outermost layer of the alumina.
  • the body is preferably formed of a cemented carbide, a cermet, a ceramic, or a high speed steel and the coated body is preferably used as a cutting tool in metal cutting operations.
  • the ⁇ - and ⁇ -Al 2 O 3 layers as well as the Ti(C,N) layers are applied by MTCVD (Medium Temperature Chemical Vapor Deposition).
  • MTCVD Medium Temperature Chemical Vapor Deposition
  • the deposition of the ⁇ - and ⁇ -Al 2 O 3 layers utilize the technique described in my copending U.S. patent application Ser. No. 09/498,334, herein incorporated by reference. In that process, H 2 S is added to the otherwise conventional MTCVD techniques and apparatus in amounts greater than 0.7 vol %, generally 0.75 to 1.7 vol %, preferably greater than 1 up to about 1.5 vol %, of the total gaseous mixture.
  • the coating process is performed at temperatures of from about 700 to 900° C., preferably 750 to 850° C., at a pressure of from about 50 to 600 mbar, preferably from about 100 to 300 mbar, for a time sufficient to form the coating, generally from about 2 to 10 hours, preferably from about 4 to 8 hours.
  • the deposition of Al 2 O 3 can be carried out at the same temperature as the MTCVD (Ti(C,N) layers, resulting in considerably shorter processes (the heating up/cooling down steps are eliminated) and the deposition of the multi-layer is carried out at relatively low temperature, resulting in no phase transformations.
  • the multi-layer coating can be composed of both ⁇ and ⁇ which can simply be controlled by H 2 S.
  • the ⁇ phase which is less stable than ⁇ should be situated in the uppermost part (i.e., top half) of the multi-coating layer, if used; and as shown earlier, MTCVD Ti(C,N) exhibits better wear resistance than TiN.
  • Ti(C,N) instead of TiN, crater wear resistance in hypo-eutectic steels and flank wear resistance in hyper-eutectic steels will be enhanced.
  • Tables 1 and 2 show a summary of the wear properties of different coating in SS1672 and SS2258 (hypo- and hyper-eutectic steels, respectively)
  • the coating material may show very different behaviors in these steels. Consequently, different coating structures have to be developed for SS1672 (thin Al 2 O 3 layers+thick Ti(C,N) layers, FIG. 2 a ) and for SS2258 (thick Al 2 O 3 layers+thin Ti(C,N) layers, FIG. 2 b ) in accordance with the knowledge of the skilled artisan. Schematics of the optimized coating structures for these steel are shown in FIGS. 2 a and 2 b.
  • Cutting tests were performed in SS1672 and SS2258.
  • the coating, according to FIG. 2 a being composed of 6 ⁇ -Al 2 O 3 layers interspersed by layers of Ti(C,N), (total multi-layer thickness 7 ⁇ m) was tested on SS1672 and a coating deposited according to FIG. 2 b , being composed of 5 ⁇ -Al 2 O 3 layers interspersed by layers of Ti(C,N) (total multi-layer thickness 7 ⁇ m) was tested on SS2258.
  • Cutting tests were also conducted using inserts having single layers of Al 2 O 3 , TiN and Ti(C, N) as well as a multi-layer of ⁇ -alumina and TiN were compared. The results are given in Tables 3 and 4.
  • FIG. 3 A detailed comparison of the behaviors of a single layer and a multi-layer coating (FIG. 2 b ) in turning SS2258, is presented in FIG. 3 .
  • the multi-layer coating is superior to the single layer SS2258.
  • the flank wear is clearly reduced by the Ti(C,N) coatings.
  • both crater wear and flank wear resistance of the multi-layer ⁇ -Al 2 O 3 coated inserts were superior to those of the single ⁇ -Al 2 O 3 coated inserts.
  • the effects of the multi-layering is very clear.
  • the lifetime of the insert is drastically increased, in particular at 200 m/min more than about 100%.
  • SS2258 hypereutectoid steel
  • a multi layering results in much more drastically reduced wear than observed earlier in hypoeutectoid steels (U.S. Pat. No. 5,700,569).
  • FIG. 4 A detailed comparison of the behaviors of a single layer and a multi-layer coating (FIG. 2 b ) in turning of SS1672, is presented in FIG. 4 .
  • the multi-layer coating is superior to the single layer also in SS1672.
  • mulitlayers of ⁇ -Al 2 O 3 with Ti(C,N) together with reduced thickness of the alumina layers enhanced the performance of the inserts over the prior art. It appears clear from the SEM micrograph that both crater wear and flank wear resistances were superior to those exhibited by the single layer. In this steel, the flank wear is clearly reduced more than earlier observed when multi-layer coatings of ⁇ -Al 2 O 3 and Ti(C,O) were investigated (U.S. Pat. No. 5,700,569).
